Application
Design takeaway
For critical design communication and feedback loops, opt for physical prototypes. For other stages, consider digital or VR models, but be aware of AR's current limitations.
How to apply
When presenting a design concept to stakeholders for feedback, consider creating a physical model, even if digital iterations are also used. For user testing involving spatial interaction, VR might be more effective than AR.
Project actions
- 01When choosing a prototyping method for your design project, think about what you need to achieve: Is it for visualising form, testing ergonomics, or communicating complex functionality?
- 02If your project requires detailed feedback on physical form and user interaction, a physical prototype is likely to yield better results than a purely digital one.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Direct comparison of multiple contemporary prototyping methods.
- +Focus on key benefits of prototyping relevant to design practice.
Limitations
The specific software, hardware, and materials used for each prototype type can significantly influence results. The complexity of the design being prototyped also matters.
Reliability & validity
Reliability could be improved by using a larger sample size and more standardized evaluation metrics. Validity is supported by the focus on core prototyping benefits, but the specific context of the study might limit generalizability.
Think critically
How might the cost and time associated with creating different types of prototypes influence a designer's choice, even if one method is theoretically superior?
Design Principles
"The tangibility and direct sensory engagement of physical models enhance their efficacy in design communication and feedback compared to purely digital or augmented representations."
Understanding the relative strengths of different prototyping methods allows design teams to select the most appropriate tools for their specific project goals. This can lead to more efficient development cycles, better stakeholder alignment, and ultimately, superior product outcomes.
What This Means for Your Design
Making a physical model of your design is often better for showing others and getting their ideas than just showing them on a screen or using an app.

Paragraph starter
Research indicates that physical prototypes often outperform digital alternatives like CAD, AR, and VR in facilitating clear communication and gathering actionable feedback during the design process. This is attributed to their tangible nature, which allows for more direct sensory engagement and a richer understanding of form and function, ultimately leading to more informed design decisions and potentially superior product outcomes.
